SCARABiEIDAE. 125 



Epipleurae distinct, narrow ; scutellum none. Caxthon. 

 Epipleurae of the elytra wide ; anterior tarsi wanting. 



Group II. DELTOCHILA. 



Anterior tibiae not prolonged at the extremity. Deltochilum. 



Sub-Tribe 2. — Coprilii (genuini). 



The gradually thickened middle and hind tibiae unfit these in- 

 sects for transporting the balls of material which serve for the 

 food of the larvae ; though some of the species do construct balls, 

 they bury them in the place where they are formed. The sexual 

 differences are frequently strongly marked, the male having horns 

 on the head or thorax. The epipleurae are always narrow, and 

 the first joint of the tarsi is elongated. The anterior tarsi are 

 wanting in some species of Phanams, and the claws are all want- 

 ing in the same genus. 



The following groups are represented in our fauna : — 



Third joint of labial palpi distinct ; 



Anterior coxa? very transverse, not prominent. Scatonomi. 

 Anterior coxae short, prominent ; 



Labial palpi dilated. Copees. 



Labial palpi subfiliform. Onites. 



Third joint of labial palpi obsolete. Ontuopuagi. 



Group I.— Scatonomi. 



Our only representative of this group is Chccridium capistra- 

 tum, a moderately small, convex, shining, bronzed black insect, 

 resembling a Histeride, with finely striate elytra, found in dung. 

 The 3-jointed labial palpi, and the transverse, not prominent, 

 anterior coxas, readily distinguish it from the other groups. The 

 claws are small, without onychium, but the tip of the last joint of 

 the tarsi is prolonged beneath into an obtuse process one-half as 

 long as the claws. 



Group II. — Copres. 



The labial palpi are 3-jointed, broad, and compressed; the 

 anterior coxae are conical, large, and prominent. The last joint 

 of the tarsi has no onychium, and in one genus the claws are 

 wanting ; in Copris the claws are small, and the inferior portion 

 of the joint is prolonged into a process as long as the claws. 

 The anterior tarsi are wanting in certain foreign Phanams; and 

 iu one genus, Deudropa3mon, from Brazil, the tarsi have only two 

 joints.
